As you continue to use Little Reader's features, importing and removing Categories to customize your Word Library, it will not be uncommon for left-over files to remain, cluttering up your Media Library folder. The Purge Unused Media function removes any media files found in the Media Library that are no longer in use by Little Reader, freeing up space in your computer.
To purge unused media, simply select the Speed Optimizations tab from the Tools screen.
Little Reader will search for any files found in your Media Library folder that are no longer associated with any Little Reader word files.
Click DELETE and OK afterward to remove unused files found in your Media Library.
